hey bought cheapy off ebay and then read the post warning not to!! turned out post were right and it didnt work right....everyone seems to say same best buying from stealers less hassle in long run an you know what your getting! think mine worked out round 70ish
 
ECP £25 surcharge for your old one works out around £55 with an all important warranty

next time search to see if your question has been asked before!
 
just bought 1 from seat and it cost £80! but be warned the ebay crap is exactly that, CRAP!
